  • Checking digital signature on EXE

    - by LTR
    My .NET exe is signed using signtool. Using this code, I can verify the validity of the certificate itself: var cert = X509Certificate.CreateFromSignedFile("application.exe"); var cert2 = new X509Certificate2(cert.Handle); bool valid = cert2.Verify(); However, this only checks the certificate itself, and not the signature of the EXE. Therefore, if the EXE is tampered with, this method doesn't detect it. How can I check the signature?

  • boost.asio error on read from socket.

    - by niXman
    The following code of the client: typedef boost::array<char, 10> header_packet; header_packet header; boost::system::error_code error; ... /** send header */ boost::asio::write( _socket, boost::asio::buffer(header, header.size()), boost::asio::transfer_all(), error ); /** send body */ boost::asio::write( _socket, boost::asio::buffer(buffer, buffer.length()), boost::asio::transfer_all(), error ); of the server: struct header { boost::uint32_t header_length; boost::uint32_t id; boost::uint32_t body_length; }; static header unpack_header(const header_packet& data) { header hdr; sscanf(data.data(), "%02d%04d%04d", &hdr.header_length, &hdr.id, &hdr.body_length); return hdr; } void connection::start() { boost::asio::async_read( _socket, boost::asio::buffer(_header, _header.size()), boost::bind( &connection::read_header_handler, shared_from_this(), boost::asio::placeholders::error ) ); } /***************************************************************************/ void connection::read_header_handler(const boost::system::error_code& e) { if ( !e ) { std::cout << "readed header: " << _header.c_array() << std::endl; std::cout << constants::unpack_header(_header); boost::asio::async_read( _socket, boost::asio::buffer(_body, constants::unpack_header(_header).body_length), boost::bind( &connection::read_body_handler, shared_from_this(), boost::asio::placeholders::error ) ); } else { /** report error */ std::cout << "read header finished with error: " << e.message() << std::endl; } } /***************************************************************************/ void connection::read_body_handler(const boost::system::error_code& e) { if ( !e ) { std::cout << "readed body: " << _body.c_array() << std::endl; start(); } else { /** report error */ std::cout << "read body finished with error: " << e.message() << std::endl; } } On the server side the method read_header_handler() is called, but the method read_body_handler() is never called. Though the client has written down the data in a socket. The header is readed and decoded successfully. What's the error?

  • Testing custom constraints in Grails App

    - by WaZ
    Hi there, I have the following as my unit test: void testCreateDealer() { mockForConstraintsTests(Dealer) def _dealer= new Dealer( dealerName:"ABC", Email:"[email protected]", HeadOffice:"", isBranch:false) assertFalse _dealer.validate() } But when I run the test I get the following error: No signature of method: static com.myCompany.Dealer.findByDealerNameIlike() is applicable for argument types: (java.lang.String) values: [ABC] I use some custom constraints in my domain class. How Can I test this? static constraints = { dealerName(blank:false, validator: { val, obj -> def similarDealer = Dealer.findByDealerNameIlike(val) return !similarDealer || (obj.id == similarDealer.id) } )

  • Patterns: Local Singleton vs. Global Singleton?

    - by Mike Rosenblum
    There is a pattern that I use from time to time, but I'm not quite sure what it is called. I was hoping that the SO community could help me out. The pattern is pretty simple, and consists of two parts: A singleton factory, which creates objects based on the arguments passed to the factory method. Objects created by the factory. So far this is just a standard "singleton" pattern or "factory pattern". The issue that I'm asking about, however, is that the singleton factory in this case maintains a set of references to every object that it ever creates, held within a dictionary. These references can sometimes be strong references and sometimes weak references, but it can always reference any object that it has ever created. When receiving a request for a "new" object, the factory first searches the dictionary to see if an object with the required arguments already exits. If it does, it returns that object, if not, it returns a new object and also stores a reference to the new object within the dictionary. This pattern prevents having duplicative objects representing the same underlying "thing". This is useful where the created objects are relatively expensive. It can also be useful where these objects perform event handling or messaging - having one object per item being represented can prevent multiple messages/events for a single underlying source. There are probably other reasons to use this pattern, but this is where I've found this useful. My question is: what to call this? In a sense, each object is a singleton, at least with respect to the data it contains. Each is unique. But there are multiple instances of this class, however, so it's not at all a true singleton. In my own personal terminology, I tend to call the factory method a "global singleton". I then call the created objects "local singletons". I sometimes also say that the created objects have "reference equality", meaning that if two variables reference the same data (the same underlying item) then the reference they each hold must be to the same exact object, hence "reference equality". But these are my own invented terms, and I am not sure that they are good ones. Is there standard terminology for this concept? And if not, could some naming suggestions be made? Thanks in advance...

  • Regex replace (in Python) - a more simple way?

    - by Evan Fosmark
    Any time I want to replace a piece of text that is part of a larger piece of text, I always have to do something like: "(?P<start>some_pattern)(?P<replace>foo)(?P<end>end)" And then concatenate the start group with the new data for replace and then the end group. Is there a better method for this?

  • Flash: Am i totally misunderstanding Event Listening?

    - by Kohan
    I don't know why but i am having trouble getting my head round event dispatching. Take this for example. someClass():Void{ this.addEventListener("onChange",someObj); } Am i right in assuming this means that someClass is listening for an onChange event and when it gets it, it is then going to fire the onChange method on someObj? Thanks, Kohan.

  • Print/save full webpage as PDF

    - by Oliver
    I need a method to be able to print/save the current full webpage as a PDF. I know it can be done if I download a PDF printer and print to that; but I need it to be done without the user having to do anything other than click a button in a webpage. I can't do it via PHP as the page is all client side content, so I'm guessing an ActiveX component? Any ideas would be greatly appreciated! Many thanks

  • How to generate real UTF-8 XML with grails without the escape characters?

    - by AngeDeLaMort
    I have been wondering why when I set the encoding to UTF-8 and rendering the XML it replace the extended characters by escape characters (or character reference) like &#x2019; instead of '? I'm using the Render method render(contentType:"text/xml", encoding:"UTF-8") {...} with a proper header render(contentType:"text/xml", encoding:"UTF-8", text:"<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n") Any idea if there is a way to write it properly? Thanks.

  • How to Form.GetChildSAtPoint?

    - by serhio
    I would like to obtain the list of controls under a given point. There is a method on System.Windows.Form to obtain a control under a point(GetChildAtPoint) but not point(GetChildsAtPoint). Is there something similar for the list of controls (if borders intersect one other): I need this because I select the objects when user clicks on the panel(I use Microsoft.VisualBasic.PowerPacks.RectangleShape as label bellow). In case if labels are superposed, user should be asked what object to select.

  • Dynamic content doesn't work when loaded with ajax

    - by Wurlitzer
    I'm trying to load some dynamic content after the user has logged in, using $.ajax, like so: $.ajax({ url: "functions.php", type: "GET", data: login_info, datatype: 'html', async: false, success: function (response) { $('#main').html(response); } }); The problem is, that some events don't work, when loaded this way. I fixed the buttons with the .live() method, but a sortable list for example, doesn't work. How can I somehow refresh the DOM, and let jquery know of these new added elements? Thanks!
